Construction method for reinforcing construction elevator foundation by means of temporary supporting structure
The invention relates to the technical field of building construction, in particular to a construction method for reinforcing a construction elevator foundation by relying on a temporary supporting structure, which comprises the following steps: backfilling backfill soil for the first time according to the height of a supporting crown beam top; main body steel bars are connected with the top of the supporting crown beam, and secondary backfilling is conducted on backfilling soil; and foundation bed construction is conducted at the upper end of the backfilled soil after backfilling, and elevator foundation beam construction is conducted on the foundation bed. The technology of layered backfilling and layer-by-layer compaction by using a small compaction machine is adopted, the compactness of backfill soil is ensured, the risk of differential settlement is reduced, the bearing capacity of the foundation is improved, meanwhile, materials such as cement and/or lime are doped in the backfill soil, the strength and stability of the backfill soil are improved, a backfill area is firmer, and the service life of the backfill area is prolonged. And the method is more suitable for subsequent building construction.
本发明涉及建筑施工技术领域，具体是一种依托临时支护结构对施工电梯基础加固的施工方法，所述施工方法包括如下：根据支护冠梁顶的高度，对回填土进行首次回填；将主体钢筋与所述支护冠梁顶进行连接，并对回填土进行二次回填；在回填后的所述回填土的上端进行基础垫层施工，并在所述基础垫层上进行电梯基础梁施工。本发明采用分层回填并使用小型压实机械逐层压实的技术，确保了回填土的密实度，降低了不均匀沉降的风险，提高了基础的承载能力，同时通过在回填土中掺杂水泥和/或石灰等材料，提高了回填土的强度和稳定性，使得回填区域更加牢固，更适合后续的建筑施工。
